Configure BFD for an IPv6 Interface on a VLAN

BFD for IPv6 interfaces is a demonstration feature on some products. For more information about feature support, see Fabric Engine Feature Support Matrix.

About this task

BFD provides a failure-detection mechanism between two systems. Use the following procedure to enable and configure BFD for an IPv6 interface on a VLAN.

Procedure

  1. In the navigation pane, expand Configuration > VLAN.
  2. Select VLANs.
  3. Select the Basic tab.
  4. Select the VLAN on which you want to configure BFD.
  5. Select IPV6.
  6. Select IPv6 BFD Interface.
  7. Optional: In the MinRxInterval column, double-click the field and type a value for MinRxInterval.
  8. Optional: In the TxInterval column, double-click the field and type a value for TxInterval.
  9. Optional: In the Multiplier column, double-click the field and type a value for Multiplier.

IPV6 BFD Interface field descriptions

Use the data in the following table to use the IPv6 BFD Interface tab.

Name Description

Interface

Specifies an index value that uniquely identifies the interface.

Enable

Enable BFD on the VLAN.

MinRxInterval

Specifies the minimum interval, in milliseconds, between received BFD control packets that the local system is capable of supporting. The default is 200 ms.

Note:

The minimum value you can configure for the receive interval is 100 ms. You can configure a maximum of 4 BFD sessions with the minimum value for the receive interval. You can configure any remaining BFD sessions with a receive interval that is greater than or equal to the 200 ms default value.

TxInterval

Specifies the transmit interval in milliseconds. The default is 200 ms.

Note:

The minimum value you can configure for the transmit interval is 100 ms. You can configure a maximum of 4 BFD sessions with the minimum value for the transmit interval. You can configure any remaining BFD sessions with a transmit interval that is greater than or equal to the 200 ms default value.

Multiplier

Specifies a value for the multiplier used to calculate a receive timeout. The default is 3.

Note:

If you configure the transmit interval or the receive interval as 100 ms, you must configure a value of 4 or greater for the multiplier.
